What Arcs Is
Arcs is a strategy game designed by Cole Wehrle and published by Leder Games in 2024. It is built around a card-driven turn structure that behaves a lot like trick-taking: each round, players compete over who leads, who follows, and who gains the initiative. It is a space-faring game of resources, ships, cities and conflict, and it plays with two to four players.
This page summarizes the structure. For edge cases, always use the official rulebook.
Where to Find the Arcs Rules PDF
The official base game rulebook and the player aid booklet are published by the game’s publisher on its resources page, and community files are also posted on the Files tab of the Arcs page on BoardGameGeek. The Blighted Reach campaign expansion has its own rulebook. Prefer the publisher’s version, because fan summaries sometimes disagree on small details such as which cards are removed in smaller player counts.
The Core Idea: Action Cards and Initiative
Arcs does not use a fixed turn order. Instead, each round starts with the player holding the initiative playing an action card. That card has a suit and a number of pips, and the pips are the number of actions available.
- The suits correspond to families of actions, such as building, moving, or fighting.
- The lead player plays a card from their hand, sets the suit for the round, and takes actions up to the card’s pips.
- The lead player may also declare an ambition (more below).
Following the Lead
After the lead card is played, each other player in turn order chooses how to respond. As commonly summarized, there are three options:
- Surpass: play a higher card of the same suit and take actions equal to its pips.
- Pivot: play a card of a different suit and take a single action from it.
- Copy: play a card face down and take one action of the lead card’s suit.
A player may also seize the initiative by adding a second card face down, which lets them lead the next round. If nobody seizes it, the player who surpassed with the highest card usually takes the lead. Initiative and its exact conditions are among the most important rules to read in the official booklet.
Actions You Can Take
Action cards let you take actions such as building, repairing, moving ships, gaining resources, battling and taking cards from the Court. Resources like material, fuel and weapons, plus relics and psionic items, feed those actions, and holdings such as ships, starports and cities build your board presence.
Battles
Arcs resolves conflict with dice. Different dice types are used for assaults, skirmishes and raids, and the results determine damage and what attackers can take. Battles can create captives and trophies, which feed some ambitions.
Ambitions and Chapters
Arcs is played over a series of chapters. A chapter ends when players run out of cards, and then Power is scored. The central scoring mechanism is ambitions. When a lead player declares an ambition, players compete to rank highest in that category by the end of the chapter, and rewards go to the leaders. The five ambitions are commonly listed as Tycoon, Tyrant, Warlord, Keeper and Empath. Each rewards a different resource or achievement. The player with the most Power at the end of the game wins, and the exact number of chapters can depend on the mode and campaign setup.
Tips for New Players
- Do not treat the lead as a chore; sometimes it is better to follow and save good cards.
- Watch which ambitions others are building toward before you declare one.
- Keep an eye on the Court, since it is an important source of new abilities.
